The digital output thing is just an inexpensive addition that would have been nice to have considering this keyboard will sell for multi-thousands of dollars in the US. I mean, my Edirol PCR-1 controller is a $300 keyboard and it has optical digital audio output as part of it's headphone jack (so does the Fujitsu laptop I'm writing this post on for that matter). Yeah, yeah arrangers are for live use - I've made that point myself, but I don't see why cheap keyboards and commonplace laptops can have digital audio but mega-arrangers can't. For the money, digital audio could and should be included in the G-70.
